Nres = 1d resolution parameter...total views will be Nres^2
Nframe = number of frames in an aquisition grouping, default =
Nres.
L = number of segments, default 1 for no grouping) ...ignored
scheme = 'spiral', 'cubed_sphere', 'mesh_icos', 'fibonacci',

saves silent_grad_Nres*.txt file in current dirctory
rawviews.N_pad is the padding paramter used, rawviews.data is view
table in array
